Materials and post-processing: beyond the printer specification

Materials reference · checked 30 October 2026

The FDA overview highlights two manufacturing details:

• Batch controls: raw materials need consistent specifications.
• After printing: cleanup, polishing or sterilization may be required, depending on the device.

It also distinguishes assessment of a finished device for its intended use from unrestricted permission to reuse its material elsewhere. A resin or metal name alone is therefore not a product authorization.
